Each channel consists of two terminal connections specific to that channel as shown in Table 2.
You can verify or adjust the accuracy for any or all channels depending on the desired test
coverage. Refer to Figure 2 and only connect the input channels required for verification or
adjustment in parallel.
Refer to Table 2 for the analog signal names of the TB-4304.
